| 摘 要： | 本文针对低纬度地区频率域化磁极存在的问题，在频谱分析的基础上，提出了一种新的滤波方法即振幅滤波法。该方法能将低纬度地区化极磁场的频谱恢复到垂直磁化磁场的频谱，大大提高了低纬度地区化磁极的精度。

| Abstract: | A new filtering method - amplitude filtering technique has been proposed in this paper to solve the problems of reduction to the pole in frequency domain in low latitude region on the basis of frequency analysis. Itcan restore the spectra of,dip magnetic field in low latitude region to that of vertical one. As a result, the precision of reduction to the pole in low latitude region has been improved greatly. |
